from the loading-the-dice dept.
Country_hacker writes "News site TBO.com is reporting ChevronTexaco has opened a hydrogen fuel station in Chino, California, and has plans to open five more. Servicing three (or more) Hyundai SUVs, these prototype fueling stations are a part of a five-year cost-sharing program put on by the Department of Energy. Could this be the 'egg' in the alternate fuels 'chicken or egg?' scenario?"

      I did some work (low-level, pressure and piping design stuff) on the trials in Vancouver for buses. This was at least 7 years ago. Our proposal didn't win. I don't remember DC as being a candidate, as it was Vancouver and Detroit at that time.

      I'd be interested in the refueling, is it from tube trailers or LH2 trailers?

      Liquid hydrogen always sounds scary, but this stuff is road transported every day via million dollar tankers. One of the big industrial gas manufacturers has a video (taken from a local TV station's collection) where a LH2 tanker overturned--nothing happened. Of course, safety and technical specialists from all over had to be called-in to placate the local authorities.

      When cold boxes are built (I know as I've designed a few), they are often stencilled on the exterior as CBOX1, PCB1 (pump cold box 1), et cetera. During shipping via Schnabel [sbiii.com] everyone wants to take a look and people worried/ignorant about technology have fits about possible nukular explosions.

        Actually, they've gone to some real trouble to make carbon-fiber-reinforced tanks that are *very* hard to bust. I've seen the test footage, and when they finally did manage to bust one (which was no mean feat), it slowly leaked the hydrogen out. What is more, when they ignited the leaking hydrogen, it just burned, Just Like Gasoline; it did not explode.

        Incidentally, leaking H2 is somewhat safer than leaking gasoline, because it tends to float up and away instead of accumulate in a growing pool on the ground.

          Hate to Reply to Myself (tm Slashdot Inc.), but i forgot one other thing: another research group has been working on storing H2 as a Nickel-Metal Hydride. Sound familiar? It's the same method used for batteries of the same name. They fill a tank with fine, fine metal powder (mostly Ni), and pressurize H2 into it. The H2 bonds to the powder at the molecular level, which means you can squeeze ~1,000 times more hydrogen into the same size tank. To get the H2 out, you actually have to apply a small amount of heat to the tank. A fraction less efficient, but much safer than your post would suggest.
          • And how heavy is a tank full of Ni and where does the initial heat come from to release the hydrogen? Why not just devise a better battery and store electricity? Sure would cut out an expensive conversion to electricity or combustion. Hydrogen is not a great fuel. Even if you can make it safe.

              They said that the process should eventually allow a 1-liter tank to hold enough H2 to give a Civic-size car a 1,000 km range (assuming it was using a fuel cell). The heat (they said it doesn't take much) comes from the battery pack (most/all fuel cellers have them).

              Now as to whether hydrogen is or isn't a 'great fuel', I don't know. But safe it most certainly can be.
            • In any compressed gas, there are two effects going on. First, some molecules are close together and are weakly (and temporarily) bound. This reduces the stored energy in the system. The lower the temperature, the larger the fraction of molecules like this (and, eventually, the gas liquefies).

        NEXT you assume only one square metre of solar cell space.... how big is your house? mine is around 8*20 metres = 160 m^2

        SO if you take my house as an example, you are looking at 160m^2 * 200w (say)per m^2 * 8 decent sunlight hours per day = about 250 KWhours per day IF i cover my entire roof with panels, plenty to power multiple cars and the house and the neighbours house etc etc.

        THE only problem with this scenario? due to a lack of widespread investment in solar technology, as opposed to oil or other fossil fuels, solar cells still cost about 5 bucks a watt, so your looking at an upfront investment of about 160 grand to cover my roof in panels. Now obviously i dont quite need that much power, but either way itll be a fair whack of money at current prices (otherwise i wouldve done it long ago).

    What needs to be done is some kind of joint effort between auto makers and fuel companies to simultaneously release H fueling stations and H powered cars. This is a nice first step, but it's not going anywhere until there is widespread adoption.

    With any luck, these hydrogen stations will mark the beginning of the end for Islamic tyranny from the Middle East. For too long, we have essentially financed terrorist operations by paying money for gasoline. They money goes to, for example, Saudi Arabia.

            But what you've missed is that it takes as much energy in fossil fuels to produce a gallon of ethanol as is released when you burn it. The benefits of ethanol as a renewable energy source are very debateable. I'd bet bio-diesel is a lot more energy positive though.

            It is going to be extremely difficult for any renewable source to take hold until all the non-renewable sources are gone.

            Not true. We're probbably never going to run out of fossile fuels, it's just going to become increasingly expensive to get them. Not all fossile fuels have equal costs in getting them out of the ground and into a useable state. Canada for instance has a trillion barrels of oil in the form of tar sand. They're very costly to extract into a useable form though. The point is that as fossil fuels become increasingly expensive renewable sources will become econmically viable. The costs associated with renewables will also likely only go down as more money+research gets pumped into them from the profits of usage.

            This is actually one of the reasons that OPEC doesn't want high oil prices. High oil prices only encourage investments in other energy sources, which eventually only undermines oil prices.

      But ethanol is a crappy idea - it's got a lot of drawbacks, and it essentially needs to be "grown". A much better alternative is the old Vegetable oil way of doing things - BioDiesel. Almost every filling station in Europe stocks Diesel and BioDiesel works in most if not all Diesel engines. The enormous benefit is the turnaround time, as it is a continuous, rather than a batch process (for those Chemists out there).

      Let's not go changing most of the mechanical parts if all we need to change is the fuel...

      BioDiesel, grown from Rape Seed etc, would give not only American's reason to get the farms up and running again, but also third world countries - a lot of farmers will grow this stuff and sell it very cheaply, to be refined elsewhere. BioDiesel _will_ revolutionise the European lorry (sorry, truck) market, such a shame that the USA won't be able to partake - you're far too reliant on petrol (the stuff you normally fill up with). 10 years, and you may be ready, Europe is ready NOW. Let us be your Guinea pig. Do you hear that [insert current UK Home Secretary]???
    • The US Ethanol effort [ethanol.org] is a lot bigger than you imagine, especially here in the midwest, where the corn that is fermented to produce ethanol is grown. All of our gasoline fuels are now blended at 10% ethanol, and the major auto makers are making cars that will run on 85% ethanol [e85fuel.com], which is provided at various fueling stations [e85fuel.com].

    This is not part of a 'chicken and egg' situation. Lack of fueling stations is not what's holding back hydrogen cars. What's holding them back is: (1) lack of range (due to the low energy density of compressed hydrogen gas, and lack of practical alternatives), (2) cost of hydrogen itself, and (3) the still very high cost of fuel cells. The last point is important, since hydrogen as a fuel makes very little sense for internal combustion engines -- since the hydrogen is made from natural gas, you might as well just burn natural gas in the vehicle, or a liquid fuel derived from gas.

    BTW, if it's oil independence you want, Fischer-Tropsch diesel fuel is already very competitive at today's oil price (it would be competitive with oil at $25/barrel.) Expect many more synfuel plants to be built if oil stays expensive.

    To make things clear, hydrogen is not a source of power. It is merely a way of transmitting or storing power. Hydrogen comes from either electricity, or is extracted from natural gas. Electricity can be "green" to various degrees. Natural gas is no more "green" than other fossil fuels.

    So, if what we're talking about is a storage/transmission system, how does hydrogen add up? Very badly is the answer.

    To store any usable quantities of hydrogen requires one of the following: extremely low temperatures, extremely high pressures, or some chemical to absorb it. Low temperatures are not practical for automotive applications because it requires constant energy input to keep it cold. Extremely high pressures or absorbing it into hydrides are sort of practical but you end up with either a very large, expensive high pressure tank that holds a small amount of hydrogen, or you end up with a large, very expensive bit of palladium or whatever that's going to hold a small amount of hydrogen.

    So getting hydrogen requires a very expensive and inefficient process which (today) is derived from fossil fuels. It can only be stored in small quantities and the storage itself is extremely expensive. Oh, it also does best with fuel cell engines which also require extremely expensive catalysts (more palladium, etc).

    So in the end we come out with numbers in the neighborhood of a $150k vehicles that has a range of 150 miles and has a cost per mile of 50 cents, just for the fuel. Sounds like a winner to me!

    Compare this to electric cars. Electricity is distributed and available everywhere. There are green sources of electricity which are cost-competitive, and improving. The big expense in electric cars is the battery. Lithium is the best choice, and it is coming down in price rapidly. Range on a lithium battery cars can go over 200 miles.

    When you look at the pros and cons, the only advantage we see in the end for hydrogen is that it can be refuelled quickly. You pump it into your car and go on, just like with gasoline. But are the downsides worth it?

    I can't help but think that this whole hydrogen thing is an enormous, almost fraudulent exercise in scamming subsidies from the government to support a technology which is outrageously expensive. I would rather see natural gas refueling stations, rather than see stations that sell hydrogen extracted from natural gas.

    I also have a feeling that part of the push for hydrogen is a push to maintain huge barriers to entry in the auto manufacturing industry. It will require enormous technology resources and patent portfolios to produce a hydrogen car. With electrics, on the other hand, anyone can do it in his garage, once batteries become available. That must be scary to the industry; they haven't faced any new entrants into the market in a long time.

    Speaking of practical, just how practical is hydrogen going to be, anyway? Unless there is a huge improvement in the abundance of energy needed to seperate hydrogen atoms from water (or methane or other sources), other methods like bio-diesel or just plain electric are going to be more pratical ways to reduce US dependence on oil.

      Just where do you think the hydrogen comes from? The cheapest way to get hydrogen is by cracking natural gas. So much for getting away from fossil fuels. Also, anyone who thinks that only water (vapor) comes out of the exhaust is wrong. That would be true if all that went into the engine were hydrogen and oxygen. Guess what? The air is 80% nitrogen. NOx formation can be a problem with hydrogen engines. The hydrogen itself also has properties that make for a bad fuel: it has such a low density that it is hard to carry much fuel and hydrogen can find the smallest holes to escape from that other gases would not.

      ...and it was produced by Standard Oil, right?
      You can make Hydrogen with a nuclear reactor. you can also make it with pretty much any steam source.
      1 cold war era nuclear bomb could potentially generate enough hydrogen to run the state of texas's autos for 2-3 months or more, if every car in texas was converted over to H.

    • Biodiesel is really what we should be concentrating on right now. Biodiesel pours right into pretty much any existing diesel engine and has only slightly less BTUs per gallon that petroleum diesel. Certainly biodiesel isn't as clean as hydrogen, but it's a whole heck of a lot cleaner than petroleum diesel and even more so than gasoline. The best part of biodiesel is the fact that you can start using it immediately in your unmodified diesel powered vehicle and not have to worry that you're going to be able t

      Wonder of wonders! I have half a BILLION DOLLARS stashed away in a Nigerian bank from the estate of the late President Mbawasa Ngimima of Upper Revolta just waiting for a way to get it out of the country. Perhaps we could work out an arrangement...
